The Simpson Heavy L-Shaped Angle HL57 is a heavy-duty utility angle engineered to reinforce right-angle connections between structural wood members in framing and timber construction. Built to a symmetrical L-shaped profile, this angle bracket is fabricated from zinc galvanized steel with a G90 coating, delivering dependable corrosion resistance where moisture exposure is a concern. Whether the application calls for corner framing reinforcement, beam-to-post connections, or paired installations requiring lateral load capacity in both directions, the HL57 provides the structural performance needed to maintain joint integrity across a wide range of wood construction scenarios.

Key Features

• Right-angle reinforcement for structural wood members - provides a reliable mechanical connection at 90 deg. corners, reducing the risk of joint movement or separation under load.
• Resistance to both uplift and lateral forces - helps keep connections secure against the multi-directional stresses that framing and timber joints commonly experience.
• Bidirectional lateral load capacity when installed in pairs - gives builders added flexibility to meet engineering requirements for connections that must perform in opposing directions.
• G90 zinc galvanized steel construction - the corrosion-resistant coating helps maintain structural integrity in framing environments where moisture or humidity may be present over time.
• Compatible with 1/2 in. diameter bolts or equivalent lag screws - lag screws of equal diameter, minimum 5 in. long, may be substituted in the beam with no reduction in load, offering installation flexibility on the job site.
• Symmetrical L-shaped profile - the equal-width legs simplify layout and positioning, helping standardize connections and reduce installation time across multiple framing points.

Why This Product

• Heavy-duty performance for demanding framing applications - the HL57 is built to handle the structural requirements of beam-to-post and member-to-member connections where a lighter-gauge angle would fall short.
• Versatile fastener compatibility - the option to substitute lag screws for bolts in the beam without any load penalty gives contractors more ways to complete connections with the hardware already on hand.
• Corrosion-resistant finish for long-term reliability - the G90 zinc galvanized coating is suited for wood construction environments where moisture exposure could compromise an uncoated connector over time.
• Domestically produced by Simpson - manufactured in the United States, the HL57 reflects the quality standards that structural connector professionals rely on for code-compliant framing and timber work.
